I agree! Your photos are fantastic and you've photographed species that I've only dreamed of seeing. You had quite a trip and this is an amazing congregation of Red-billed Pintails and White-faced Whistling-Ducks!! So cool!
@Summer Tanager have you read the trip report? I have posted a link in the forum. Maybe it can help you build your own trip or just learn more about the sites? Alarobia Lake is in the middle of Antananarivo, the capital, and is a true heaven lost in the middle of rice paddies and growing constructions.
